There you can monitor my progress which i try to update daily. I would have taken some pictures but i dont have the digicam at the mo. Hopefully get some up soon.

P11GT,

Looking forward to read about your project!!

You have my hit on your page once a day!!

Overlap in cams is when the intake and exhaust valves are open at the same time. This can be an advantage to N/A motors but not really benifical to turbo cars.

so G, i'll try to get hold of the spec for mine, as they were custom, i dont know if they'll still have the data, but i'll try. I'll pass them onto you, let you have a look, cos i dont have a clue.

Ive bought the oil pressure gauge but i need to know how much psi the engine should be running at with the turbo. As its my first turbo of any kind, i dont know what to expect. Any clues anyone?

[P10DET]

Good work mate! Best of luck to you.

What are you using for engine management?

[P11GT]

Heres your answer, below is a picture of my old HKS filter and theres also the unichip, which will control everything.
Can anyone help me out with my following questions? Have a look at the picture below first, its arrowed to two pipes.


The arrow on the left points out the rocker breather pipe, which ive been told to reconnect to the low pressure side of the turbo i.e. behind the MAF sensor/ before turbo inlet. I could however just put a rocker breather filter on and not bother reconnecting it at all. Would this statement be correct????

The arrow on the right points out another pipe which apparently goes to the 'stepper motor' which controls idle????? This one i dont have a clue what to do with when installing the turbo. Where should this be?? pressure side or non pressure side??

Help anyone??

[b-b00gie]

I believe you are correct on the first one. The one in question though I'm not sure of. Never looking into it yet. I guess I'd better find out also.

The GTiR pistons should be arriving within the next few days. Ive been told to use new oil on reassembling the engine, which is what i had planned, also, ive been told to change the oil after about 1,000 miles. This is because of the fine metal shaving caused by the new pistons bedding in. Is this true or just common sence. I suppose thats why dealer insist on a 1,000 mile oil change on new cars.

[P11GT]

Well, ive been down to the dealers and picked up my pistons, well three of them anyway, the others still on order.

Ive had a word with a GTiR tuner and he says by fitting the GTiR pistons, i'll see 8.3:1 compression but however, since ive bought a 2mm metal gasket, it'll lower it further to 7.8:1 He assures me thats its fine and will just be similar to a tuned GTiR.

Any thoughts anyone???

Well, Kevin, I see you're in the final phase! Looking good!

[P11GT]

er........ well not quite. ive just encountered a few problems. expensive problems to be exact. Im updating the site just now, so check out the updates pages.

[v_knot]

hey mate, good work on the T conversion.

Are you having two projects running at the same time? I find it hard to follow as your last update you were talking about changing a T15 to a T28 using T3 compressor housing and in your very last paragraph you said you want to do it right the first time on the Primera.

[P11GT]

yeah, sorry for the confusion.......
its just the one T conversion going on and thats the Primera. Its just that ive not long discovered that the turbo i originally had and wanted to fit, doesnt meet the requirements, so now im having one made to suit, namely a T28/T3 Hybrid with 360 degree thrust bearing.
